President Barack Obama directed the Environmental Protection Agency (EPA) today to reconsider a Bush-era decision that stopped California and more than a dozen other states from setting their own stricter limits on auto emissions.

Jerry Karnas is the Florida Climate Project Director with the Environmental Defense Fund. He says Gov. Charlie Crist has been a very vocal leader on the California
Clean Car standard.
